Do you have any tips for my flight to Newcastle?
We've got the lowdown on how to make your journey an enjoyable experience. Follow our tips and you'll be hightailing it through airport security and having a blast in Newcastle in no time flat. What to pack in your hand luggage:
  • First and foremost, pack your passport, important documents, wallet and vital medications. Next, you'll want some entertainment to help pass the time. A juicy novel and a phone crammed with your favourite shows are always good options. If you hope to take a quick snooze, a quality neck pillow and a pair of noise-cancelling headphones will also be useful. Finally, make room for a toothbrush and some facial wipes so you'll arrive looking and feeling fresh.
Do not pack the following items in your hand luggage:
  • Pack all your full-sized bottles of shampoo and hairspray in your checked baggage. Any liquids or gels in your carry-on suitcase larger than 3.4 ounces (100 millilitres) will be confiscated by authorities. Sharp objects, like your trusty Swiss Army knife, and dangerous goods which are flammable or explosive, such as aerosol cans, flares and poisons, are also prohibited.
What to wear on a flight:
  • Comfort should be your main priority when deciding what to wear on board. Loose, breathable clothing is a sensible choice, as are enclosed shoes like sneakers.
  • Deep vein thrombosis (DVT) can pose a risk on long-haul flights. It results from blood clotting due to poor circulation, so do some gentle leg and foot exercises in your seat and consider wearing compression socks or tights.
How to get through airport security fast when flying to Newcastle?
It's simple — be prepared. We've rounded up some handy tips and tricks for a fuss-free trip through security. Watch out Newcastle, here you come:
  • Security personnel first need to check that you have a valid passport and matching travel documents before you can proceed any further. Keep them within easy reach.
  • Next up, both you and your hand luggage must be X-rayed. To speed things up, remove anything that might trigger the alarms. Personal belongings such as your coat, belt and earphones need to go through the machine.
  • Electronic devices like laptops and phones will also have to go through the machine for inspection. No need to worry though, you'll be back online in no time.
  • Remove liquids and gels from your carry-on luggage. They usually need to be sent through the X-ray scanner separately. Each item should be no larger than 3.4 ounces (100 millilitres) and everything must fit in a quart-size (one litre), clear zip-lock bag.
  • Lightweight sneakers are a sensible footwear choice as you're less likely to have to remove them when passing through security. Hiking boots and heavier-style shoes are usually subjected to extra screening.
  • Airlines won't allow any sharp or pointed objects in the cabin. If you need to bring these kinds of items, pack them in your checked baggage.
